Isn't that asking the impossible though? From the way it's told in the article, Chipotle combed as exhaustively as they could through their ingredients in the immediate aftermath and as soon as possible, searching for the culprit.

But since it takes several days for the illness to set in (four, in the case of the one guy they profiled), even an immediate reaction was too slow to have a hope of figuring out which ingredient caused the poisoning.
